Disturbingly, your link includes Carbon capture and storage from a fossil power plant, which has never been demonstrated practically and is basically a scam at this point, pushed by oil companies.
Second, you are conflating subsidy with cost. If everyone switches to electric trucks, cost is enormous, but subsidy is zero because private sector pays for it themselves. For electrics freight trains, cost could be lower, but the government has to pay for it.
However, everyone with a grasp of physics knows that freight train is more efficient, so focusing on subsidy is stupid
